ABSTRACT:
A fiberscope comprises an elongated flexible tubular member having an axially extending channel, an operator unit 2 for performing an endoscopic observation or treatment through the channel, a mounting recess 21 formed in the operator unit, an adapter 8 which can be mounted in the mounting recess, and a spray module 7 having a spray nozzle 33 which can be connected to the adapter 8. As the spray module 7 is pressed to the adapter 8, the valve mechanism of the spray module 7 is opened so that a compressed gas is ejected from the tip of the tubular member through the bore 42 of the adapter 8 and the gas passageway 23 in the operator unit 2, and, thus, deposits on the open end of its internal channel are removed with jets of a gas.
